Current status:

ClojureScript can now compile both its analyzer & compiler w/o errors. Can eval non-trivial ClojureScript exprs from within the JS host.
Performance reading, analysis & compilation within bootstrapped ClojureScript has been optimized to be roughly within a factor of 2 of ClojureScript JVM (varying perf between engines).
Master is successfully being used in various contexts:

The following enumerates the remaining tasks:

Ensure perf is good.
Ensure defects are addressed. Many have bootstrap label: JIRA Query
Determine if shared bootstrap REPL code will be included and implement.

* you can use the CLJS API reference to help identify imported macros and related Clojure types

cljs-in-cljs from 2012

As a point of reference, https://github.com/kanaka/clojurescript is a previous project to bootstrap the ClojureScript compiler. It is fairly dated since it was forked from the main tree on Nov 16th, 2012, however, it was self-hosting and allowed for a fully browser-based REPL: http://clojurescript.net/ A presentation of the project from Clojure West 2013 is here: http://www.infoq.com/presentations/cljs-in-cljs
